Abstract: 1,232,547. Heating and cooling granular material. GLANZSTOFF A.G. 11 April, 1969 [13 April, 1968], No. 18731/69. Headings F4G and F4U. Apparatus for the continuous thermal treatment of pourable granular material comprises at least one, e.g. as shown, two, treatment zones 3 delimited at the bottom by fittings 11 and laterally by vertical walls 2 and a flow stabilization zone 4 between the lowest fittings and a discharge zone having two parallel walls and two converging walls 6, the height of the stabilization zone 4 being greater than the product of its width (measured transverse to discharge slot 7) and the tangent of the slope angle of the material, and the angle between walls 6 being smaller than 0À8 times the difference between 180 degrees and twice the slope angle of the material. A substantially "plug" flow of material through the apparatus is achieved as long as the width of the treatment zone is less than 1500 mm. Fittings 11 are gas inlets or heating and cooling elements. The ratio of the width of the discharge slot 7 and the width of the treatment zones 3 is preferably less than 0À1 in order to dam the flow of material for control of residence time. A discharge roller 8 adjusts the quantity of material discharged. For drying polyethylene terephthalate chips a lock-chamber bunker 13 is provided to prevent premature exposure to the atmosphere. The apparatus may comprise several arrangements as in Fig. 1 disposed side by side with a common feed pipe 1 and a common discharge funnel 14 (Fig. 5, not shown). The common interior walls may be omitted (Fig. 6, not shown) but in this case the treatment zones lying above each of the several discharge zones are considered separately for selection of dimensions.

When the crucible is used within a gas-tight envelope the coil is also enclosed in the envelope.

Abstract: 1,250,460. Parachutes. STENCEL AERO ENG. CORP. 15 Oct., 1968 [27 Dec., 1967], No. 48794/68. Heading B7G. A multi-canopy parachute apparatus has a ballistic canopy spreading device consisting of a cylindrical housing 6, with a circular flange 8, supporting about 30 circumferentially spaced projectile driving pistons 14, in radial bores 12, and, an explosive cartridge 11, which on ignition drives the pistons 14 and projectiles 10 radially outwards. The ballistic spreading device is arranged so that a different portion or the skirt of each canopy is adjacent a different arcuate portion of the annular series of projectiles, and, so that each projectile can be connected by tape 18 to a different part of the canopy concerned. Each canopy is packed in a pleated fashion by folding along the centre of each gore 21 and along the edge 22, as shown in Fig. 4. The pleats of opposite halves of the canopy are arranged so so that they can be intermeshed, as indicated by the dotted and solid lines, thereby finally forming a stack of pleats. In order to keep the suspension lines separate, those 19b, which are not connected to the projectiles, are run from the canopy skirt through cylindrical bores formed matching grooves 23 in adjoining sides of the projectiles 10, where each bore effectively maintains one line until cartridge 11 is fired and the projectiles 10 are drawn outwardly to free the line 5. The canopies can be suitably stored in a container by stacking the stacks of pleats then folding the resultant in a " Z " fashion and inserting into the bag so that the spreading gun is at the top of the bag.

Abstract: 1,259,093. Packaging; delivering sheet material; feeding webs. TEXALES (PLANT) Ltd. 23 Dec., 1968 [22 Sept., 1967], No. 43359/67. Headings B8C and B8R. Measured lengths of carpet or linoleum are cut from a supply roll 12 and are then rolled up for dispatch between driven rollers 40, 41, 42, 43 which are arranged to move apart to accommodate the roll of carpet and at a speed that governs its tightness. When it is complete, the roll is wrapped in a sheet of paper fed in laterally. Storage rolls from store 10 are controlled by flaps 13, 14 to pass in turn on to a belt 16 on rollers 15 arranged to unroll the carpet and feed it on to a conveyer 17. It is metered by photoelectric cells 21, which control axial and/or angular tracking of feed rollers 19 should the carpet not travel in a straight line, before passing to a feed table 20 and cutting table 22 where it is clamped at 23 and cut by a blade 24 when sufficient has passed on to a measuring platform 26 having a further photo-electric cell detector 29 which is preset to the required carpet length. At station 30, Fig. 2, which bridges the measuring platform, wrapping paper from roll 31a is fed on to a further measuring platform 34 to a further photo-electric detector 35 and adhesive is dispensed on to one edge of the paper. The paper is then cut at 37. The rolling station 39 comprises the roll-up rollers 40, 41, 42, 43 each including a series of friction axially spaced wheels (44, Fig. 3, not shown), those on rollers 40 and 42 having pointed teeth, those on roller 41 have flattened teeth, and those on roller 43 are smooth. A plurality of spring-guides 45 lie between rollers 40 and 41 in the gaps between the friction wheels 44 and are mounted between additional rollers 46, 47. The front edge 48 of these springs catches the leading edge of the carpet to turn it at 48 to initiate the rolling up, Fig. 5. The carpet is fed from conveyer 25, via conveyer 57 to the nip of the rollers 40-43. The upper rollers 40, 41 are vertically movable, their weight being counterbalanced by weights (58, Fig. 3, not shown) whose effectiveness is controlled by an actuator (62) and dash-pot (63), so as to accommodate the growing roll of carpet and to control its density. Meanwhile the springs 45 are raised clear of the carpet by rotation of a lifting roller 47 as the carriage 49 of the top rollers 40, 41 rises, Figs. 5 and 6. As the end of the carpet passes photo-electric cell 71, the paper wrapping starts to pass down inclined platform 38, so that it overlaps the carpet-end and finally wraps the roll of carpet. The rolled carpet is freed by raising the top rolls 40, 41 by means of the actuator (62). Exhausted supply rolls are rejected at chute 75.

Abstract: 1289861 Vehicle power steering HOBOURN EATON MFG CO Ltd 30 Dec 1969 [6 Jan 1969 23 June 1969] 822/69 and 31683/69 Heading B7H A vehicle power steering arrangement including a rack-and-pinion mechanism 13, 14, comprises a cylinder 16, a piston assembly having a piston 25 and piston rod 10, the cylinder including an annular valve member 29 encircling the piston rod, an annular operating shaft 15 carrying the valve member 29 at one end thereof, said valve member 29 forming with the piston assembly a valve operable to control the motor, and resilient means urging the valve member to a neutral position relative to the piston assembly and permitting limited axial movement of the valve member relative to the piston assembly to control a supply of pressure fluid to move the piston in the same direction as the initiating movement of the valve member relative to the piston. In one embodiment (Figs. 1, 1a) the valve member is adjustably screwed to the end of operating shaft 15 and has an annular land 36a co-operating with a groove 37 in the piston rod 10, to define two variable size restrictions for controlling the motor. The rack 14 is secured to shaft 15 so that movement of the rack 14 to the left (in Fig. 1) results in similar movement of the valve member 29. Pressure fluid entering nozzle 45 passes into chamber 41, through conduit 40, through a conduit in the valve member to recess 38 defined by lands 36a, 36b thence to groove 37, conduit 46 and chamber 47 to urge the piston to the left. (In the neutral position of the valve member 29 the fluid would pass from groove 37 to chamber 42 and thence to nozzle 44.) Movement of the rack and hence the valve member 29 to the right blocks off the restriction between groove 37 and recess 38 so that pressure builds up in chamber 41 thereby facing piston 25 to the right. The valve member is urged to its neutral position by spring 33. The ratio of the effective areas at sides 41, 47 of the piston is equal to the ratio of the aperture size of the first restriction (i.e. that between groove 37 and recess 38), to the aperture size of the two restrictions (the second restriction being between groove 37 and chamber 42). Preferably the ratio of effective areas is 1:2 (i.e. the restrictions are of equal aperture size). In another embodiment (Fig. 4), not shown, the valve member is integral with a shaft (15) at one end thereof and the rack is integral with the shaft (15) at the other end thereof. The spring (66) for cutting the valve member is located remote therefrom and acts on the rack.
